UPDATE: According to Disney Music Group, the single is not called 'Pieces of a Heart.' It is still unknown what her next single will be called, and when it will drop!

Does Demi Lovato have a new song on the way? According to a rumored tweet by MTV's Sway Calloway, Lovato's 'Pieces of a Heart' will debut on 'MTV First' on Feb. 13 at precisely 7:49PM ET.

The tweet was reportedly posted by Sway and then deleted, though it can be seen online in screenshot form. Maybe he wasn't supposed to reveal the news just yet and his bosses asked him to remove the posting. If the alleged tweet was accurate, 'Pieces of a Heart' could be the lead single from Lovato's fourth album, which is due sometime this year.

What might 'Pieces of a Heart' mean if it's the actual song title? It could be a sad song about a heart shattered by breakup. Or maybe it's a metaphor about love. We like the second explanation, especially since the track would be premiering on the eve of Valentine's Day.

February would be a good time for Lovato to drop a new single, since 'X Factor' is on hiatus. Her last album, 2011's 'Unbroken,' proved to be a successful comeback effort with hit singles 'Skyscraper' and 'Give Your Heart a Break.'

Just don't wait on Lovato to confirm or deny the report about the new song on Twitter, because she's taking a break from the social media site.
